Mill/Turn Centers with Integrated Robotic Part Handling

Quicktech i-42 ROBO and i-60 ROBO 4-axis mill/turn centers from Absolute Machine Tools, Inc. (Lorain, OH) feature integrated 6-axis Mitsubishi robots for fast, automated loading and unloading of medium-diameter (i42: 42 mm/1.68 in, i60: 60 mm/2.36 in) bar stock. In addition to carrying out highly productive turning, these machines can perform complex milling with standard live tools. An optional 360 deg B-axis further extends milling capabilities. Quicktech machines are distributed in North America exclusively by Absolute Machine Tools. The Mitsubishi S-series 6-axis high speed robot automatically loads, unloads, or turns over parts weighing up to 13 lb. An optional multi-tray pallet handling system enables untended operation. The robot is contained within the machine and is positioned to allow unimpeded operator access for machine setup and operation.

The i-42 ROBO and i-60 ROBO machines operate in 4 axes (5 axes with the optional B-axis), with a 15 hp high torque turning spindle that features C-axis capability, a 2 hp live tool milling spindle, and capacity for 17 tools (23 tools with B-axis). A standard DIN-173-42B collet chuck provides capacity for 42 mm bar, while an optional with a 60 mm collet or 6 in, 3-jaw chuck offers 60 mm bar capacity. The machines’ innovative tooling arrangement provides part-making flexibility and efficiency. A 3-axis (4-axis with optional B-axis) gang-type vertical tool post serves the main spindle with 6 OD turning tools, 5 ID turning tools, and 3 radial and 3 axial live tool heads. The tool post also provides Y-axis motion for off-center milling operations. Rigid tapping is standard, as is the Kennametal KM-25 quick-change system that minimizes tool change time.

A matched CNC system combines a Mitsubishi M80A control, featuring a 260 mm (10.4 in) LCD, with Mitsubishi servomotors and amplifiers for top reliability and performance. Standard machine features include a bar feeder interface, parts conveyor and catcher, chip conveyor, collet chucks and a 400 psi coolant pump. Machine frames and all major components are heavy Meehanite cast iron. In addition, the i42 and i60 ROBO machines utilize large 35 mm Hiwin roller type linear guideways and double-anchored, pre-tensioned 32 mm ballscrews. “Robotic part handling, combined with the speed, efficiency, and flexibility of the Quicktech i-42 and i-60 mill/turn centers, creates an integrated, highly productive manufacturing package,” said Steve Ortner, the president and owner of Absolute Machine Tools.
